BREAKDOWN GUN.

SPECIFICATION forming part of Letters Patent No. 461,679, dated October 20, 1891.

Application tiled January l2, 1891- Serial No. 377,457. (No model.)

T U/ZZ whom it may concern,.-

Be it known that I, GRANVILLE HENRY, a citizen of the United States, and a resident of Nazareth, Northampton county, Pennsylvania, have invented certain Improvements in Breech-Loading Fire-Arms, of which the following is a specification.

Myinvention relates to that class of breechloading tire-arms in which a side-acting bolt is used for locking the barrehthe object of my invention beingJto'provide a simple def-/wice for' moving the bolt so as to unlock the barrel, and for moving the hammer to the position of half-cock simultaneously with the unlocking of the barrel. This object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in whichk Figure l is a perspective view of the lock mechanism of a breech; loading gun constructed in accordance with my invention, the side plate being detached to show the internal parts. Fig. 2 is a perspective view of part of the lock mechanism, showing some of the devices in a different iposition from that represented in Fig. 1. Fig. 3 is a detached perspective view of that part of the mechanism to which my invention specifically relates.

Fig. 4 is a side view of the lock mechanism,

showing the parts in a position similar to those shown`in Fig. l. Fig. 5 is a like view showing the parts in a position similar to thosew represented in'Fig. 2. Fig. 6 is a View partly in plan and partly in section on the lines l 2, Fig. fi; and Fig. 7 is a like view, the section being on the lines 3 4, Fig. 5.

A represents the lock-casing, which has a rearwardly-projecting portion A for entering the stock of the gun and forwardly-projectin g cheek-pieces A2, between which ts the pivot-plate of the barrel structure, said c heekpieces having openings@ for the reception of the pivot-pin of the barrel.

4The barrel is locked in position by means of a laterally-sliding bolt B, suitably guided in an opening in one side of the lock-casing and having a stem b projecting into a socket (l in the otherside of the lock-casing, as shown in Figs. 6 and 7, a springf being interposed between the head of the stem and the base of the socket, and this spring having a tendency to draw the bolt B inward, so as to cause it to engage with the usual slot in the pivotplate of the barrel, and thus locking said barrel. The hammer D of the gun has within the lock-casing the usual hammer-lever or tumbler D', which is acted upon by the main spring F, connected to the tumbler by a link F', said tumbler having the usual full-cock,

notch .fr and half-cock no tch`/for'engagement with the toe Vof thc'trigger G. The unlocking-lever J occupies a position on the top of the lock-casing and is secured to or forms part of a stem I, which is free to turn in suitable bearings in the top and bottom of the lock-casing, and has two cam-surfaces t' and m formed upon it. The cam-surface t' is formed by cutting away one side of the stem I near the lower end of the same, and this cam acts upon a toe n on the rear end of the locking-bolt B, as shown in Figs. `b and 7, so that movement of the unlocking-lever J from the position shown in Fig. l to that shown in Fig. 2 effects movement of the stem I from the position shown in Fig. 6 to that shown in Fig. 7, thereby moving the locking-bolt B laterallyto such an extent as to unlock the barrel of the gun, the spring f tending to restore the bolt to locking p0- sition'as soon as pressure is removed from the lever J. The cam m consists of the beveled base of a recess formed in the rear of the stem I, and this cam acts upon a forwardly-projecting tongue s on the tumbler D, so that the same movement of the stem which etfects the projection of the lockingbolt B will effect a lift of the forward end of the tumbler, so as to permit the trigger to engage with the halt-cock notch of the same, the hammer being thereby lifted to the position of half-cock. (See Figs. 4t and 5.) An eitective but extremely simple device for the purpose is thus provided, which does not require any material change in the other parts of the lock as now constructed.

Having thus described my invention, I

claim and desire to secure by Letters Patentl. The combination of the lock-casing and the laterally-sliding locking-bolt therein, having a laterally-projecting sternV contained in a recess in said casing and having an enlarged head, a spring surrounding said stem and acting upon the head of the same, the top lever, and the lever-stem having a side cam IOO acting upon the locking-bolt to laterally problerV to move the hammer to .the position of 1o ject the saine against the action of the spring, half-cock, substantially asv specified.4 `substantially as specified. l In testimony whereof I have signed my 2.
